TIRE-BENDER.

SPECIFICATION forming part of Letters Patent No. 387,848, dated August 14, 1888.

Application filed July 30, 1887.

To aZZ whom it may concern.-

Be it known that I, Jncon F. Bnnnnn, of Columbia, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Tire-Benders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apportains to make and use the same. I

Herctoforc in socalled tire-benders in order to remove the tireit has been necessary by various means to draw the upper or center roll laterally through its bearing in the frame. This class of tirebendcrs cannot be used to ad vantage for the reason that collars for keeping the tire from warping would require too much time to be loosened and fastened every time the roll was to be removed.

Another objectionable feature is the necessity of having one bearing in theframe as large as the roller itself, this principle creating an undue amount of friction.

The object of my invention is to provide a center-roll bearing for a tire-bending machine which will allow the said roll to be removed from the frame in a vertical direction, both bearings of said roll being any diameter less than the body of same, said roll being adapted to have warping collars on it,when so desired, which need not he removed in order to take said roll from its position in the frame.

Another objectionable feature has been to provide adjustable bearings for the end roll, to which a portion of the gearing is attached, and also for the driving-shaft,which is adapted to engage with said end roll.

My invention consists, first, in a tire-bending machine having in combination with the frame a bearing for the journals of the center roll, composed of a cast-iron ring with alever attached. Said ring is open at the top, so that the shaft can be removed. \Vhen the ma.- chine is working, the lever is turned one hundred and eighty degrees, bringing the ring on top of the shaft, in which position the shaft is locked.

It further consists, in combination with the frame, of adjustable bosses to support the end roll thereby. Said roll has a lateral adjustment.

Renewed April 9, 1888.

Serial No. 370,032. (No model.)

It further consists, in combination with the journal-bearing, of bosses for the driving-shaft having vertical adjustments.

Figure 1 shows a front view of the bearing for the top shaft; Fig. 2, a vertical section through the center of Fig. 1. Fig. 3 is a top view of same. Figs. 4 and 6 show the boss for the end roll, and Figs. 5 and 7 show the boss for the driving-shaft.

In Figs. 1, 2, 3, A represents the bearing of top shaft with alever, a, attached to it. This bearing is supported around its sides by the main frame B. At the ends A is supported by a lug, b, and the wrought-iron plate 0. Plate 0 is fastened to the castiron frame B by means of set-screws D. W'hen the machine is in use, the lever a is turned one hundred and eighty degrees, as shown in dotted lines, in which position the shaft E is entirely secured. Bearing A is kept on its place by the lever a, that rests on the plate a at d d.

In Figs. 4 and 6,Fis the bearing for the shaft G. fis a lug that slides in a groove, 9, of the castiron frame B, and the lug h slides behind the frame B. These two lugs keep the boss from turning. The holem will be drilled after the gearings are finished on the shafts, and an exact fitting can be attained in this manner. If the bolts n are made a smaller size than the hole in, the gearings can, after being used, be adjusted all that is necessary to take up the lost motion.

In Figs. 5 and 7 holes 1010 are made oblong, so as to make the bosses adjustable.

I do not limit myself to any particular construction of partially-rotating boss or actuating-lever; neither do I restrict myself to the particular construction of actuatinglever herein shown and described.

My improvement involves'a radical departure in the construction and principle of withdrawing the center roll vertically from the frame of a tire-bending machine, the invention consisting, broadly, in a tire-bending machine having the central rollerbearing bosses actuated by suitable levers adapted to partially rotate in the franic,whereby,when in one position, said central roller may be removed vertically from theframe, and when in the reverse said roll cannot be removed in any direetion.

Having thus described my invention, what I claim,and desire to secure by Letters Patent, 1s-

1. In a tire-bending machine, the combination,with the central roller and the frame, of partially-rotating bearingbosses for the upper central-roller journals, said bosses being actuated by suitable levers and adapted to fit sockets in said frame, and provided with openings corresponding with similar ones in said frame through which the roller-journals may be removed when so desired, substantially as shown.

2. In a tire-bending machine, the combination, with the frame, of a bearing-boss for the 15 end roller, the same being bolted to the frame and adjustable, substantially as set forth.

3. In combination with the frame, a bearing-boss for the driving-shaft bolted to the frame, and adjustable, substantially as shown 2c and described.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
